Bernardo
Recamán (Bogotá, 1954) is a British trained (University of Warwick)
Colombian mathematician and mathematics teacher. Like so many of his
generation he was brought up on Martin Gardner´s Mathematical Games
columns in Scientific American, with which he came across in his school
library. Since 1977 he has taught at several schools and universities
in Colombia, and at the Waterford Kamhlaba United World College of
Southern Africa in Swaziland. He has compiled several puzzle
collections, most recently Ejercicios cerebrales (Ochenta juegos,
acertijos y desafíos mentales para que se divierta y su cerebro no se
deteriore), Editorial Grijalbo, Bogotá, 2012. One of his main
interests is in graphical number theory (teoría gráfica de los números),
which explores the many close and beautiful links between the theory of
numbers and graph theory. He has contributed several sequences to Neil
Sloane´s OEIS, including Recamán´s Sequence, thus named by Sloane
himself.
